Crunchyrolls encoding have been really fucking dodgy lately, Dia no Ace was barely watchable, last KlK had an incredible amount of grain and so on. So if you are patient go for fansubs they know their shit.

And about 1080p, it's not worth it even if the source material was 1080p with CRs encoding it wouldn't matter, seriously last Dia no Ace looked the same in 360p and 1080p, sure makes you happy when you actually pay for their shit.
